A transmitter device designed for transmitting media packet streams over a data network. The device addresses the challenge of efficiently transmitting diverse media formats by providing multiple input media channels, each capable of receiving media with a specific format. The device includes one or more transmission ports for sending out the media packet streams. A processor within the device is responsible for packetizing the received media channels, transforming them into media packet streams suitable for network transmission. A controller governs the processor's operations. Specifically, the controller instructs the processor to create a first media packet stream comprising one or more media channels that share a common format. Simultaneously, it directs the processor to generate a second media packet stream containing one or more media channels also sharing a common format, but this format is distinct from the format of the media channels in the first stream. The number of media frames included within each packet is dynamically determined based on the sample rate and bit depth of the media channels grouped together within that specific packet stream.
2. A transmitter device of claim 1 , wherein the controller further automatically determines the number of frames per packet of each packet stream, wherein the number of frames per packet of the first packet stream is different to the number of frames per packet of the second packet stream.
This invention relates to a transmitter device for managing packet streams in a communication system. The device addresses the challenge of efficiently transmitting multiple packet streams with varying frame requirements, ensuring optimal bandwidth utilization and synchronization. The transmitter device includes a controller that dynamically adjusts the number of frames per packet for each packet stream. Specifically, the controller automatically determines the number of frames per packet for a first packet stream and a second packet stream, where the number of frames per packet in the first stream differs from that in the second stream. This allows the device to adapt to different data types, network conditions, or application requirements, improving transmission efficiency and reducing latency. The controller may also manage packetization timing, ensuring that frames are grouped into packets in a way that maintains synchronization between streams while accommodating their distinct frame rates or payload sizes. This capability is particularly useful in systems where multiple streams with different characteristics, such as video and audio, must be transmitted simultaneously without compromising quality or performance. By dynamically adjusting frame-to-packet ratios, the transmitter device optimizes resource allocation, minimizes packet overhead, and enhances real-time communication in applications like multimedia streaming, teleconferencing, or industrial automation. The invention improves upon prior systems by providing flexible, adaptive packetization tailored to each stream's specific needs.
3. A transmitter device according to claim 2 , wherein the controller further controls the processor to cause the first media packet stream to be sent to a multicast address, and the second media packet stream to be sent to a unicast address.

10. A transmitter device according to claim 1 , wherein if the format of a media channel changes, the controller further operates to automatically regroup the media channels into media packet stream having the same format.
This invention relates to transmitter devices used in media streaming systems, particularly addressing the challenge of maintaining consistent media packet stream formats when media channel formats change. The transmitter device includes a controller that dynamically manages media channels to ensure seamless streaming. When a media channel's format changes, the controller automatically reorganizes the media channels into a new media packet stream where all channels share the same format. This prevents disruptions in playback and ensures compatibility with downstream devices. The transmitter device may also include a media channel selector for choosing channels to include in the stream and a media channel formatter for adjusting channel formats.
